gaspower Posted March 5, 2005 Share Posted March 5, 2005 Hello, I have a question about setting up my Klipsch surround system with Comcast. I just purchased a Klipsch system with a KSW-10 sub, but I notice that the green light on it is not always on when it should be. If I am informed correctly, the green light means that the sub is getting signal that the system is showing at least some sort of surround sound, but I notice when I view a DVD the light is green and it seems to be working, but when I view a HBO show in dolby 5.1 through the Comcast DVR box the light is red. I am using a Pioneer Elite VSX-54TX receiver. Can someone tell me where to diagnose the problem. Thanks JR Quote Link to comment Share on other sites More sharing options...
speed3 Posted March 5, 2005 Share Posted March 5, 2005 Try turning up the volume on the receiver for a few seconds and the sub will probably kick on. The sensitivity on the "auto on" circuits for many subs are pretty lousy IMO. If this doesn't work, possibly you have your speaker settings set to large, and therefore your sub is not receiving a signal when on cable? I doubt it, but it's possible. What are your speakers, and what is your avr? What mode are you in with cable? Do you have it set to stereo, surround, what? Quote Link to comment Share on other sites More sharing options...
sivadselim Posted March 5, 2005 Share Posted March 5, 2005 after complaining and waiting many months for a cable box with digital audio (optical and digi. coax) output, i've noticed that comcast broadcasts very few channels in true DD5.1 in my area. it really pissed me off. only 2 of my HBOs are really capable of it and only 2 of my SHOs, and even then, not all the material broadcast on those channels comes across as DD5.1. all the rest are broadcast in DD2.0 (at best) which my auto-detecting receiver is then setup to process for surround as Dolby ProLogicII. make certain that the channels you are trying are truly being broadcast in DD5.1. my cable box's on-screen display (remote's INFO button) will tell me when it's DD5.1, as well as my receiver, since it's set up to auto-detect.

kc0433 Posted March 5, 2005 Share Posted March 5, 2005 I don't have Comcast, but I have Dishnetwork and this seems to be the case for them as well. I have two boxes: my HD box (in my living room), and a regular one (in the bedroom). The HD box is the only one that gets Dolby 5.1 if it's broadcast. In my bedroom it may say it's broadcast as that, but it only come in DD 2 channel. My neighbor and I were just complaining about this same thing the other day!

It is the cable provider's job to fit as much information through one signal as possible...this means only a partial number of channels will have DD5.1. Their bandwidth is not unlimited. Digital cable means all of the channels (digital and analog) are digitized then compressed to pass through the system in the same amount of space that normal cable occupies. In short, there's no problem. Some channels are DD5.1 and some aren't. I tend to prefer Cox over Comcast to begin with, so you may get better performance with them if you have a choice and want to look into it. Nothing we can do about the rest except use Pro Logic II.

kelA Posted March 5, 2005 Share Posted March 5, 2005 I was thinking it was a bandwidth issue as well. On a side note, I have Insight cable, and the other day I was watching 'Finding Nemo' on the Encore channel and they actually had it broadcast in 6.1 DD. I was pleaseantly surprised. I still can't get over the mixing that was done for a cartoon. Unbelievable. Quote Link to comment Share on other sites More sharing options...
sivadselim Posted March 5, 2005 Share Posted March 5, 2005 yeah i figured that it was a bandwidth thing. i just wish that comcast would have told me to expect limited channels in 5.1. i wouldn't have pestered them for the correct cable box.

Agent Eagle Posted March 5, 2005 Share Posted March 5, 2005 You will notice, if your receiver can auto sense DD signal, that it will decode in DD on almost every channel... That's not to say that it is putting out a true DD signal, but it is decoding stereo in to 5.1, to the best of its ability.... Beats listening to it in stereo, any day !!

DD5.1 isn't a choice with only 2 channels of input. Quote Link to comment Share on other sites More sharing options...
